So with the Nash shoot on this past RAW, do they still let Punk adlib his material by letting him keep it all to himself or does he have to let his "victims" in on exactly what he's about to say beforehand?

Like does Vince just trust him to just go out there and say what needs to be said, giving him the carte blanche to just say what he wants on the fly? Does Vince still need to approve anything etc etc (ie. Just go out there and say what you want, just make sure to be entertaining)

For example, seems like Cena and Nash didn't know what was coming and they seemed caught off guard when Punk verbally owned both of them.

And Nash seemed lost for words and seemed legit embarrassed and had no comeback at all, hence the "stumbling on his words"

Also when Punk mentioned Cena's failed bodybuilding career attempt, Cena seemed mad embarrassed and had the look on his face like "Fuck, that was embarrassing, that's why I'm smiling to cover up my nervousness"

I read that Punk and Nash did not discuss the interview before hand, but whether or not that's true, who knows.

I think if the people don't know it makes it more "real" and it comes off better. I mean, heck, in the Nash segment, there were times when it was obvious Punk was stalling for something to say. "I like wafflehouse." Punk just covers his stalling amazingly well.
